When using Entity Framework, in an effort to track down bugs or performance problems, it’s very handy to see what SQL Entity Framework is generating and sending to the DB when you run a lambda/linq query or indeed make a call to SaveChanges().

This is easy once you know how. Simple add this.Database.Log = x => System.Diagnostics.Debug.WriteLine(x); to the constructor of your database context class (the one that derives from DbContext):

Afterwards you should see all the queries Entity Framework is sending to the DB in your output window.
